In the present study, antifungal activity of Plakobranchus ocellatus collected from the southern waters of Qeshm Island in the Persian Gulf against Candida albicans. C. parapsilosis and C. glabrata, has been investigated. Acetonitrile, ethanol and phosphated buffer saline (PBS) as organic and aqueous extracts were prepared from the whole body tissue. The effects of seven concentrations of the extracts were tested through well-diffusion method. Maximum and minimum inhibition zones were estimated for acetonitrile and PBS extracts both in 2000 concentration (µg/ml) against C. parapsilosis and C. albicans, respectively. The most effects of extracted compounds were seen in 600, 900, 2000 and 3000 (µg/ml) concentrations. The aqaous extract compared with organic extract had a low effect that can be indicating a little amount of antifungal compounds with nature of protein and temperature-sensitive. In conclusion, it could be said to obtain the bioactive compounds in extracts with more inhibition diameter purification and extraction of secondary metabolites is necessary.

Anzali wetland¡ one of the most important ecosystems¡ located in the south of the Caspian Sea (lat. 37º28΄ N: lon. 49º25΄ E)¡ receives a large amount of urban¡ agronomic and industrial swages. Nonethless it is a main place to brees¡ to grow up and to take winters for waterfowls. Twelve Common Moorhen (Gallinula chloropus Linnaeus¡ 1758) have collected alive from four stations on Anzali wetland¡ during April 2010. Histopathological investigation were shown clear alterations in liver tissues withdegeneration of hepatocytes¡ pigments macrophage aggregation¡ rupture of cells with dilation of diss space¡ congestion and haemorrhage¡ hemosiderin pigments aggregation. Aggregation of leukocyte infiltration¡ capillary dilation¡ hypertrophy¡ degeneration and shrinkage of the cells¡ affected portion of the kidney¡ glomerular expansion and absence of the Bowman’s space¡ tubular epithelial cell hypertrophy¡ were also observed in kidney tissues. Results of the present stude were revealed that kidney and liver tissues of Common Moorhen can be investigated as a pollution bioindicator in Anzali wetland¡ due to their relatively long period of wintering migratory and also high polluted body of ecosystem in Anzali wetland area.

This study was carried out in three inter tidal zones in the Iranian coast of Gulf of Oman, in 2010 to identify the species belonging to Family Ocypodidae and to investigate effect of monsoon on ecology of crabs. Two species of genus Uca (U. sindensis and U. iranica) from Jask and Khour-Khalasi study area and one species of genus Ocypode (O. rotundata) from Vanak beach were identified. The results were used to verify previous reports on species identification. Monsoon was found to affect distribution and frequency of these crabs. The maximum and minimum relative density were observed in pre-monsoon (May, 9.33 individual/m2) and monsoon (September, 6.38 individual/m2), respectively. Dense distribution of Uca was found in the muddy beaches of Khour-Khalasi and the genus Ocipode in the sandy beaches of Vanak area.
